Answer:

Step-by-step explanation:

y = k*x                    This is the formula for a direct variation.

  • y = 20
  • x = 4                        Substitute these values into the direct variation

20 = 4 * k                        Divide by 4

20/4 = 4k/4

k = 5

Answer: the constant of variation is 5

When we choose to do cosine we do adjacent/hypotenuse so it would be...

Cos(32)= x/23

Than solve for x

X= 19.18 o 19.2

Answer:

x=4 and y=2

Step-by-step explanation:

Name the triangles as ABC and DEF,

Now, since both the triangles are congruent by HL rule, therefore

3y=x+2                      (1)

and x=y+2                (2)

Substituting the value of  x=y+2  in equation (1), we get

3y=y+2+2

2y=4

y=2

Therefore, Putting y=2 in equation (2),

x=4

A symbol used to name one or more parts of a whole or a set, or a location on a number line is a?​

Answer:

Fraction

Step-by-step explanation:

Fraction is a symbol that represents a part of a whole. It consists of a <em>numerator</em> and a <em>denominator. </em>The numerator is the number above the fraction bar (also known as "Vinculum), while the denominator is the number below the fraction bar. The denominator is the total number of equal parts in a whole.

Examples of Fraction: \frac{1}{2}, \frac{2}{7} and \frac{5}{8}.

In the first example, \frac{1}{2}, 1 is the numerator, while 2, is the denominator.

<u>Additional Information</u>

When the numerator is smaller than the denominator, the fraction is called <em>"proper fraction."</em> On the contrary, when the numerator is bigger than the denominator, the fraction is called <em>"improper fraction."</em>
